Web Services und DPWS


Abstract


The usage of the Service Oriented Architecture (SOA) paradigm currently changes the point of view on many enterprise applications. SOA allows the creation of modular and clearly defined software architectures that ensure a high grade of interoperability and reusability. Because of the resource-constraint networked devices play a very significant role for the distributed data processing, it is necessary to advance the SOA paradigm to embedded device networks.

The presentation describes the Devices Profile for Web Services Specification and usage of the SOA and Web Services. Also will be discussed architecture of the DPWS gSOAP Stack. DPWS defines a minimal set of implementation constraints to enable secure Web service messaging, discovery, description, and eventing on resource-constrained endpoints. The primary goal of this technique is the extending Web Services with full featured service based metadata exchange, eventing and discovery.
